This is just awful. Why did Microsoft do that?
The recent libtiff updates in this area were necessary so that libtiff
works properly in 64-bit applications. This is supposed to be the
prototype for lfind:
void *lfind(const void *key, const void *base, size_t *nelp,
size_t width, int (*compar)(const void *, const void *));
It seems that the only cure is to add Windows specific code to handle
this specific case.
